HAN MU DO? or HUN mu do?

Hi, just wondering if anyone here has any experience with Han Mu Do. My instructor's master was trained by Dr. He-Yong Kimm, who (according to his website for the World HMD Association) developed Han Mu Do, "a balanced Korean Martial Art, comprised of punches, kicks, joint locks, throws, grappling, weapons, ki, history & philosophy."
Sounds like a great art.
